Nobody vulnerable, partner, South, dealt and opened one spade. West overcalled 2C.
Sitting North, I called 2H holding (s) xx (h) KQT8xx (d) xx (c) Kxx. (All x's are 7 or lower.)
Partner bid 3d, so I bid 3S (see why below) and partner raised to 4S. He had 14 hcp points (plus a singleton and doubleton for distribution), with 5-5 in spades and diamonds and we went down one.
Partner accused me over overbidding. With 8 hcps, I would have bid 1NT, but West's overcall precluded that option. So I said that my 2H suggested a strong suit, not a "two over one" hand, and a desire to compete. Partner also expected three spades for my three spade bid, I said that this bid was a"preference" for his first suit with my two cards in each, not a desire to go to the four level.
Did I, in fact, overbid? Or did partner take my bids out of their proper context?
