Well, this is becoming interesting, I scent victory in the air. A simple diagonal pass to.. Kilburn High Road.

Really, only one option open. Have to do a passing lateral to: Knightsbridge

It occurs to me, and this may be the subject of a book way too far, but if you add up all the topics in the proposed book and the maintenance manual, you are not far from a 'build your own concertina' book... Jigs, materials, tools and a series of detailed descriptions and drawings. Simon

Well, that is unprecedented, with laterals extended the only move possible is : Kentish Town West.

Is there no way you can just get McAfee to allow the site? It isn't actually a risky site, McAfee is just giving a false positive. Frankly McAfee is one of the worst antivirus programmes. Just google "McAfee cr*p" to get a feeling for what people think of it. Microsoft Security Essentials is free, solid, doesn't take up system resources and runs quietly in the background. It is popular, free and good. On your Android tablet, it is probably down to the browser you are using. The site runs fine on Chrome. On the iPhone 4S try it on Chrome, Mercury or Safari. If you use Mercury you can change the User agent ( sounds complex but it isn't) to fool a website into thinking you are running different browsers, one of these settings will work. Simon

And of course Tunebook and Tunepal give you access to thousands of playable ABC files score displayed for you to play along to. I know at least Tunepal is available for Android devices. Check for YouTube vids of these in action. Simon

Well, here it is, the feint out west to: Hanger Lane Damn, hate setting it up. Thought I had it until that Central Line transfer.

Sometimes sellers have zero feedback because they decide to go on ebay to sell a particular item, not because they are a scammer. Most scammers hijack good accounts. So feedback is not always a useful indicator. Easiest way, rather than rushing to report a listing if you are unsure, is to contact the seller and ask a few relevant questions that can only be answered if they have the item in their possession. Ask for a phone number, ask to hear the instrument over the phone. I've bought, and sold literally hundreds of items on eBay, some very expensive. Not been scammed once. I'm careful, but nonetheless I have huge confidence in the system. But anything with odd payment methods, or a buy-it-now for an item that should run to auction is best avoided.

I've only ever played a bifurcated lateral once before, I know it only really can be played on the southerly pass from Bank, but this is pretty classy championship play so I'll throw it in now. Might just set me up in 5 moves for a famous "Crouch Hill glide" into MC. Shoreditch High Street

I guess the thing I was not sure of is whether the instrument needs complete retune, ie it is in an old tuning and needs bringing to modern concert pitch, which is the type of tuning I was describing, or whether it has a couple of reeds a little "off". Simon

I'd recommend AP tuner as another good PC tuner, it has a clear display and will also dynamically display the note on a graph as well. I've tuned a few concertinas with it including a couple of Wheatstones. For me, and I don't class myself an expert, concertina tuning is something not to be undertaken lightly, not to be started unless you have time and inclination to finish, and requires organisation. I make up tuning tables to keep absolute track of my work, and as each note is tuned I note down the results. Just knowing exactly which reed you are working on, and working steadily and consistently is vital. I spent a solid weekend tuning my 64key Aeola, and then played it in for a week, then spent another whole day, making final adjustments to reeds that were not quite right in terms of sounding at consistent pressure. Getting the set of the reeds right is as much an art as the actual tuning, and some reeds can be troublesome. At the end of the process you should have most of the reeds within one or two cents. Tuning at consistent pressure is important too. For me tuning is as much about organisation and consistency and having your work area prepared, comfortable and well laid out as it is about the mechanics of filing reeds. Simon

After moves reeking of historical and futuristic redolence, I thought it time to bring things to a head with an Olympian counter thrust across taking us away from the yawning trap laid 2 moves ago, Here we go Stratford International

If its a harmonium you're after, ( I know nothing of Yamaha Harmoniums) then you could do worse than search on eBay. I bought a lovely Bina harmonium on EBay about 5 years ago. There are a lot on there. Best not to go for a transposing ( sliding keyboard) type. They can be a bit unreliable. Mine has a coupler which you can select, which plays the notes an octave lower at the same time as the ones you are playing. Usually the range is around 3 1/2 octaves. Harmoniums are wonderful instruments and you get a huge amount of instrument for your money. And a lot of pleasure. Simon

Well, just to force a lateral. Willesden Junction

Can only duck south to Colliers Wood
