I've been talked into playing constructive 1M-2M raises showing 7-10 and exactly 3 card support. Then I get dealt Jxx/xxx/Qxxx/Kxx, partner opens 1S, pass to me, I cleverly respond 1NT (forcing) thinking I'll correct back to spades next. 4th seat bids 2H, partner 2S, then opp raises to 3H so the auction is: 1♠ - P - 1NT - 2♥ 2♠ - 3♥ - ? Clearly I want to compete to the 3 level with a known 9+ card fit right? But partner took my 3S as a 3 card limit raise, bid game; 4S goes down one. Is this a common way to play 1M-2M? Is it really worth it to play this way, the idea being we can make more marginal game tries? Other pros/cons?
