Jon Derrick's bidding problem: K92 643 A87 AKJ2
2M would have been natural with extras. 2N would have been 11-15 3=1=4=5 or 1=3=4=5. (1 can be a canapé) He will be 54+, either minimum opener or extras without a splinter.
Jordan/Truscott 2NT
We play a transfer structure after 1M - (X) from 1N (showing clubs) upwards, so: 1M - (X) - 2M-1 as 3+ 1M - (X) - 2M purely pre-emptive 1M - (X) - 2N as 4+
direct seat overcalls 1NT
Over 1m - (1NT) we play Asptro: 2: and another, 2 and another Natural after 1M - (1NT)

English tournament entries
I'm unable to attend this year's event because of other unforeseen commitments, but having experienced the event last year, I was finishing the final weekend already saying I doubt I'd attend for the whole week this year, if any of it. In terms of from a junior ...
Jon Derrick's bidding problem: J AJ2 9852 A8542
2 is just Kokish. I've taken this hand from a Camrose match that was on Vugraph, so it's the player's methods so I'm not 100% sure. Speaking in terms of my partnership, we generally bid 2 waiting on all negatives/semi-positives. I think control ...
