Red vs white, Matchpoint, Partner opened normal 1H in 3rd seat, RHO bids 3C, holding: ♠AKxxx ♥10x ♦xx ♣Qxxx I immediately felt unhappy. Knowing that even if we don't have game, it's likely to get at least 300 if I can whip, unfortunately, it just cannot be reached since double is for takeout. If I pass, I would put too much pressure on partner. What if his hand is bare minimum? We probably will get a quiet 100 or 150, sth cannot be too satisfied. So I decided to double. Just as I expect, parnter bid 3D and I had to convert to 3H. Parnter had: ♠x ♥Q9xxx ♦KQJxx ♣AJ struggled for a while, and -200 wasn't even too bad(avg below). But I hate the result. Is there anything I can improve, or it is simply sth wrong with the modern theory of takeout double?
